2024年9月27日 · A high troponin level is generally considered to be any level above the 99th percentile of the upper reference limit (URL) for a given population. Specific values can vary depending on the assay used, but typically, a troponin level above 14 ng/l is flagged as elevated.

2014年11月20日 · What level of troponin indicates heart attack? The level of troponin that indicates a heart attack is the level above the reference range. For example if the normal reference range is listed as 0.00 – 0.40. Then 0.41 is technically positive although very weakly so, and 10 is very positive.
